My dad has had a bone-on-bone knee problem that has prohibited him from doing everything he wanted to do. So, all he would do is sit around the house. Nobody could take him out as he couldn't transfer from a wheel chair to a car. Is it possible that within 1 week, his mind could deteriorate so much as we are planning to put him in a nursing home as soon as a bed is available. My mom (90 y.o.) and I (63 y.o. daughter) cannot care for him any longer. He has been in this particular nursing home for short stays here and there and loved it--people always around, 24/7 care, things to do.
